Re: Need help finding 9B blueprint info

Exposed frame rails on 1911 and earlier franklins were body color on the outside and black on the inside- except for the front frame horns which were body color on the inside where exposed.

Starting in 1912, frame rail sides were covered by aprons and the exposed portions of the frame were body color- perhaps everything except what was behind the aprons. Since anything with color was hand varnished, I believe only exposed areas were varnished, but cannot say for certain re the sides of the rails on 1912-1916 cars under the side aprons, for example.

On the early cars, I have seen the inside of the rails and the underside of the body hand painted black enamel. At Some point the factory switched to creosote for the frame rails. I don't see any reference on the drawings until series 9. And then could it still be possible they they might have painted enamel over the creosote?
